HV9961LG-G Frequently Asked Questions (FAQs)
-
A good PCB layout for the HV9961LG-G involves keeping the high-voltage traces short and away from sensitive analog signals, using a solid ground plane, and placing the input and output capacitors close to the IC. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
-
To ensure proper thermal management, make sure to provide adequate heat sinking, such as a thermal pad or a heat sink, and ensure good airflow around the device. The HV9961LG-G has a thermal pad on the bottom of the package, which should be connected to a heat sink or a thermal pad on the PCB.
-
The recommended input capacitor is a 10uF to 22uF X7R or X5R ceramic capacitor, and the recommended output capacitor is a 10uF to 22uF X7R or X5R ceramic capacitor. The capacitors should be placed close to the IC and have low ESR to ensure stable operation.
-
The HV9961LG-G can be configured for different output voltages by adjusting the feedback resistors (RFBT and RFB) and the output voltage sensing resistors (RSNS and RVCC). The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
-
To minimize EMI and EMC issues, use a shielded enclosure, keep the high-voltage traces short and away from sensitive analog signals, use a common-mode choke on the input, and ensure good decoupling of the input and output capacitors. Additionally, follow good PCB layout practices and use EMI filters if necessary.
